The Technisat Skystar HD2 card (Azurewave AD SP400 clone) has now been
used successfully with the current mantis tree.
It is necessary to use szap to set DVB-S2 mode first, even if the
transponder you want is DVB-S (discovered by chance). If this isn't
done then it does not lock on to the frequency.
So you do the following:
szap -r -p -l UNIVERSAL -t 2 -a <card> <channel>
CTRL-C that after it has settled, then:
szap -r -p -l UNIVERSAL -t 0 -a <card> <channel>
Then (leaving the above line running) you can do:
cat /dev/dvb/adaptor<n>/dvr0 > file.mpg
and it then records error-free video.
As mentioned previously you need to change linux/drivers/media/dvb/
mantis/mantis_vp1041.h before building the drivers. Change the line:
#define MANTIS_VP_1041_DVB_S2 0x0031
to
#define MANTIS_VP_1041_DVB_S2 0x0001
This will let the driver detect the card properly on bootup due to its
different subsystem IDs, otherwise the frontend isn't registered.
HTH,
Tim.
